Broadly, there are two different models for structuring a One for the World chapter. Each offers different advantages and disadvantages.
E-Board and Student Ambassador Model
This model includes a core membership comprising a fairly lean e-board with very specific executive roles, and a broader periphery of Student Ambassadors (SAs). SAs serve to increase your reach and serve as your future leadership pipeline -- energetic SAs are good candidates to replace e-board members in the future -- but aren't expected to contribute in a planning or logistical capacity.
Pros: Lean core structure makes communication among e-board easier and reduces managerial strain on Chapter Leaders.
Cons: Chapter has relatively low capacity to execute additional initiatives or events. SAs may fall out of the loop or become demotivated if they are not managed well. In this formulation, the VP of Student Ambassadors is a crucial role and should likely be split between two of your most diligent and charismatic e-board members.
Committee Model
This model includes a core membership of e-board members, who oversee various committees. General members then choose to join one of the committees. In the past, these have included (among others):
- Outreach committee
- Marketing committee
- Onboarding committee
- Tabling committee
Pros: Broader structure provides the chapter with more capacity for executing initiatives and events, and also results in more people taking the pledge.
Cons: Wide dispersal of responsibility can significantly increase the time CLs spend managing and supervising, rather than conducting outreach and tabling.
